Econometric Estimation Of Groundwater Depth Change For The High Plains Aquifer, Jonathan R. Sims
Econometric Estimation Of Groundwater Depth Change For The High Plains Aquifer, Jonathan R. Sims
Department of Agricultural Economics: Dissertations, Theses, and Student Research
This article presents a new method for estimating changes in depth to groundwater at a yearly, county level and incorporates these estimates as the dependent variable of econometric models for the High Plains aquifer. The High Plains (Ogallala) aquifer underlies eight states in the central United States and is the primary source of irrigation water for this large food producing region. The stock of groundwater is a finite, non-renewable resource with minimal recharge in most areas. Many fields of study, including hydrology and agricultural economics, are interested in depth to groundwater changes because they serve as a proxy for estimating …

Water of poor quality can directly impact the budget of water available for key user groups. Despite this importance, methods for quantifying the impact of water quality on water availability remain elusive. Here, we develop a new framework for incorporating the impact of water quality on water supply by modifying the Water Supply Stress Index (WaSSI). We demonstrate the usefulness of the framework by investigating the impact of high salinity waters on the availability of irrigation water for agriculture in Louisiana. The WaSSI was deconstructed into sectoral components such that the total available water supply could be reduced for a …

There are pressing concerns about the interplay between agricultural productivity, water demand, and water availability in semi-arid to arid regions of the world. Currently, irrigated agriculture is the dominant water user in these regions and is estimated to consume approximately 80% of the world’s diverted freshwater resources. We develop an improved irrigated land-use mapping algorithm that uses the seasonal maximum value of a spectral index to distinguish between irrigated and non-irrigated parcels in Idaho’s Snake River Plain. We compare this approach to two alternative algorithms that differentiate between irrigated and non-irrigated parcels using spectral index values at a single date …

Study scope
The scope of the study is summarised below;
Review existing data and previous work,
Visit Carnarvon (1 day), inspect water system facilities and convene Stakeholder Workshop No 1 with representatives from Carnarvon Growers Association, Gascoyne Water Co-operative and DAFWA. Agree 3 – 4 possible system configuration options to be investigated.
Obtain and examine existing water quality data for artesian bore(s) incorporated within the study. Assess probable long term water quality and pumping heads.
Develop preliminary design details for the agreed options in terms of pre-treatment, desalination and other system modifications required (eg bores, pump …

Irrigation represents a significant portion of the total production cost for crops. Because of this it is important to have your water tested to ensure that it is suitable for the crops you are growing, and to aid in developing management plans that might help alleviate existing issues such as high salt levels or high alkalinity. The Arkansas Water Resources Center (AWRC) in cooperation with the UA Cooperative Extension Service offers several analytical packages to assess the quality of your water resources. This document is intended to provide guidance to farmers on collecting water samples for analysis and understanding the …
