Irrigator Responses to Changes in Water Availability in Idaho's Snake River Plain
… irrigator responses to previous changes in water availability is critical to building effective institutions that allow for efficient and resilient management of water resources in the face of potentially increasing scarcity due to climate change. Using remote sensing data, I examined …

Spectral analysis of hybrid bermudagrass placed under various combinations of nitrogen and water availability
… turfgrass quality for instantaneous nitrogen and water application correction. Such a test has been made on hybrid bermudagrass 'Tifway' [ Cynodon dactylon (L.) Pers. x C. transvaalensis Burtt-Davy] through a 2-year field study at the Center for Urban Water Conservation in the city of North Las …

Can phytoliths from Sorghum bicolor, a C4 plant, be indicators of past water availability?
The reconstruction of past water availability is vital to our understanding of past societies. One of the principal requirements for early state societies is a complex farming system employing irrigation. Early irrigation regimes are likely to have been ephemeral and so would no longer be visible …

Riparian Seedling Establishment Defined by Sediment Mobilization and Water Availability In a Gravel Bed River
… not necessarily maintain a connection with the water table, but must grow deeper than the depth of scour during the following fall/winter. The length of the establishment period depends on the date of the last stream recession, and the date stream flow increases to mobilize sediment. This …

Interactive effects of elevated carbon dioxide concentration and water availability on field-grown soybean (Glycine max)
… in elevated [CO2] will decrease plant and canopy water use, conserving soil moisture and ameliorating drought stress. Additionally, stimulation of A by elevated [CO2] often results in increased root biomass, and this is predicted to improve plant access to soil water, enabling avoidance of drought …

Elephant space use in relation to ephemeral surface water availability in the eastern Okavango Panhandle, Botswana
… the landscape such as vegetation productivity, water sources and anthropogenic activities drive the movement of elephants can help in understanding patterns of movement. It can also help to inform the establishment and alignment of protected areas, wildlife corridors and identification of …

Effect of irrigation on fertilizer nitrogen requirement, economic returns, and water availability in a corn-soybean rotation
… precipitation does not consistently meet crop water needs, there is extensive research documenting the value of irrigation to increased and/or stabilized yields. Delaying nitrogen (N) applications into the growing season supports more accurate N recommendations and reduces potential for N loss; …

Quantifying the Impact of Climate Change on Water Availability and Water Quality in the Chesapeake Bay Watershed
… gas (GHG) emissions. The Chesapeake Bay and its watershed are subject to the largest and most expensive Total Maximum Daily Load (TMDL) ever developed. It is unclear if the TMDL can be met given climate change and variability (e.g., extreme weather events). The objective of this dissertation is …

Evaluation of irrigation water demand and agricultural land use in relation to surface water availability in Chongwe catchment.
… irrigation activities, competitiveness in water use which have caused water stress and conflicts in some catchments. Some water availability assessment works in Chongwe Catchment have been done by various researchers but very little work has been done on assessment of water demand. Some of …

Using Water Budgets and Isotope Analysis to Explore Water Availability in Low Flow Conditions: Hartley Pond Case Study
… seasonal changes to the volume and timing of water flowing through a reservoir provides valuable information for responsible resource management. Hartley Pond is a reservoir in Duluth, Minnesota, that is formed by a dam on Tischer Creek. Solar forcing to the reservoir elevates the summer water …

The analysis of water availability indicators and access to available water in the developing, semi-arid, rural setting
… people did not have access to improved drinking water; the majority lived in the rural, water scarce regions of lesser developed nations. Global discussions of water scarcity had begun in the mid-1970’s, and over the following 30 years, several water availability indicators evolved to try to …

Temporal Changes in Surface Water Availability: Patterns of Seasonal Shift on Water Stress in the Conterminous US Under a Changing Climate
… is nothing more valuable on the planet than water. Our lives depend upon it. Climate change is already having an impact on the United States (US) and water stress will be one of the problems we increasingly face in coming decades. Regional research has shown that one or another part of the …

The Influence of Elevated Carbon Dioxide and Water Availability on Herbaceous Weed Development and Planted Loblolly Pine (Pinus taeda) and Coppice Sweetgum (Liquidambar styraciflua) Growth
… were exposed to CO₂ (ambient and elevated) and water (water stressed and well watered) treatments for approximately one growing season in closed top chambers. Weed growth had an effect on tree growth, but the amount of variation in tree biomass explained by weed biomass was very low. It appears …
