Download or read book Australian Deserts written by Steve Morton and published by CSIRO PUBLISHING. This book was released on 2022-02-01 with total page 543 pages. Available in PDF, EPUB and Kindle. Book excerpt: Australian Deserts: Ecology and Landscapes is about the vast sweep of the Outback, a land of expanses making up three-quarters of the continent – the heart of Australia. Steve Morton brings his extensive first-hand knowledge and experience of arid Australia to this book, explaining how Australian deserts work ecologically. This book outlines why unpredictable rainfall and paucity of soil nutrients underpin the nature of desert ecosystems, while also describing how plants and animals came to be desert dwellers through evolutionary time. It shows how plants use uncertain rainfall to provide for persistence of their populations, alongside outlines of the dominant animals of the deserts and explanations of the features that help them succeed in the face of aridity and uncertainty. Richly illustrated with the photographs of Mike Gillam, this fascinating and accessible book will enhance your understanding of the nature of arid Australia.
Download or read book Anthropogeomorphology of Bhagirathi Hooghly River System in India written by Balai Chandra Das and published by CRC Press. This book was released on 2020-10-27 with total page 585 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Bhagirathi-Hooghly Basin in India is one of the most densely populated regions in the world and is undergoing rapid transformation of its natural landscape induced by human interventions, such as mushrooming of dams and barrages, deforestation, and urbanization. Human activities and interventions on basin landforms and the processes that shape those landforms have accelerated at an alarming rate. This book uses spatio-temporal analysis to understand the major anthropogenic signatures on land use and land cover changes and the impact these activities have on the landforms and processes of the Bhagirathi-Hooghly River and its sub-basins. It answers the what, where, why, and how of the anthropogenic signatures involved. Recent case studies on the impact of anthropogenic signatures on fluvial forms and processes make this book a useful resource for students and researchers in the earth sciences, local governments, urban planners, and all concerned with rural developments. Features: Explores for the first time the new concept of anthropogeomorphology for the river basin—an emerging field Analyses the impact of anthropogenic activities, especially the construction of dams and reservoirs, and urbanization on major fluvial landscapes using advanced geospatial modelling techniques Investigates human interference in river systems, their effects on the dynamics of the river, and the livelihoods of the people residing along the river Addresses issues related to geology, geomorphology, geography, planning, land use, and land management areas Fills the need for data-driven governance and policy decisions for the future of urban-industrial growth in India.
Download or read book Contributions on the Status of Arid lands Research written by Eugene S. Simpson and published by . This book was released on 1969 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: Essentially all exploitable ground water of the Australian arid zone is contained in the pore spaces of relatively flat-lying sandstones and limestones, which occur within the major sedimentary basins and cover about half of the arid-zone land surface. In each basin the aggregate thickness of the porous rocks is hundreds to thousands of feet, and they are interlayered with various rocks not bearing water, thus producing artesian or semiartesian conditions in many places. Although the quantity of stored water is immense, most of it accumulated during the past tens to hundreds of thousands of years; at least half of it is too mineralized for use in irrigation. The annual recharge from rainfall, though unknown in amount, is undoubtedly only a very small fraction of the amount in storage, and perhaps even less than the annual amount currently pumped from wells. Outside the sedimentary basins, small to moderate supplies of ground water may be obtained from fissures in the older crystalline rocks, or from relatively thin surficial deposits of unconsolidated sand, if the local water table is not deeper than the depth of fissures or the bottom of the sand.

This book was released on 2011 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: [Truncated abstract] A 932 ha subcatchment and its associated wetland suite, located in the semi-arid wheatbelt region Western Australia, was investigated in this study. The lower part of the subcatchment exhibits environmental degradation due to altered hydrology resulting from clearing of deep-rooted perennial vegetation. Two main potential threats exist; firstly, upgradient migration of hypersaline groundwater from a regional primary saline valley floor; secondly, increased water and solute loads due to enhanced recharge within the local subcatchment. The hydrological function of the subcatchment and individual wetlands, and uncertainties relating to spatial scales of influence was investigated through combing physical hydrological and hydrochemical methods. A long-term trend of rising groundwater levels within the study area is evident since the clearing of vegetation, and levels have continued to rise since 2006 at about +0.06 m/yr. A ten-fold increase in the TDS at a hyposaline wetland since 1970 indicates active discharge of both stored and replenished water and solutes to the lower catchment. These trends are occurring in spite of a declining regional rainfall trend since the mid 1970's. The aquifers in the lower discharge area appear to be near full capacity although the subcatchment is yet to reach a post-clearing hydrological equilibrium. Significant groundwater TDS and density gradients occur across the study area, increasing rapidly down gradient in both the unconfined and semi-confined aquifers. The ionic compositions of groundwater, surface water and rainfall are dominated by Cl- and Na-, with overall composition being largely proportional to seawater. Cl-/Br- weight ratios indicate that halite dissolution is unlikely to be a primary factor in elevated ionic concentration. Hence, solutes are chiefly sourced from marine-derived aerosols in rainfall. Elevated nutrient concentrations (high N and lower P) were observed, although the absence of algal blooms in wetlands indicates that P is likely a limiting nutrient. Fractionation enriched stable isotopes (eD and e18O) and greater ion concentrations are observed in the deep hypersaline semi-confined aquifer compared to the regional primary saline valley floor aquifer. This indicates the occurrence of reflux brines beneath the hypersaline wetland, resulting in the export of solutes to the underlying aquifers. Seasonal changes in both ionic and stable isotope (eD and e18O) composition within the deep hypersaline semi-confined aquifer further suggest that water and solute exchange is driven by both groundwater head and density gradients. Excess recharge in the upper recharge domain is expressed down gradient at the lower discharge domain as both groundwater discharge and enhanced surface water flows...

Download or read book Hydrogeology and Groundwater Resources of the Perth Region Western Australia written by William Angus Davidson and published by . This book was released on 1995 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: The current groundwater abstraction within the Perth Region is about 300 x 10[to the power of 6] m[cubed]/year. Under present landuse conditions, and from flownet and water-balance analyses, this study has shown that the maximum total and sustainable groundwater abstraction from the unconfined and confined aquifers of the region is about 500 x 10[to the power of 6] M[cubed]/year. However, with further urban development and increased groundwater recharge from stormwater catchments, this value may be raised to about 600 x 10[to the power of 6] m[cubed]/year or twice the current groundwater abstracdon. Current rates of abstraction are therefore well within sustainable limits, and significant additional abstraction can occur.
