In coastal China, there is an urgent need to increase land area for agricultural production and urban development, where there is a rapid growing population. One solution is land reclamation from coastal tidelands, but soil salinization is problematic. As such, it is very important to characterize and map the within-field variability of soil salinity in space and time. Conventional methods are ...

The response of salinity in Apalachicola Bay, Florida to changes in water management alternatives and storm and sea level rise is studied using an integrated high-resolution hydrodynamic modeling system based on Curvilinear-grid Hydrodynamics in 3D (CH3D), an oyster population model, and probability analysis. The model uses input from river inflow, ocean and atmospheric forcing and is verified ...

Rice is cultivated in the Mekong River Delta of Vietnam under various cropping systems and cultivation techniques, influenced largely by environmental conditions. This paper describes a study on the dynamic changes in rice cropping systems in response to changes in agro-hydrological conditions resulting from infrastructure interventions to prevent salinity intrusion. Multi-date cloud-penetratin...

In arid irrigated regions, the proportion of crop production under deficit irrigation with poorer quality water is increasing as demand for fresh water soars and efforts to prevent saline water table development occur. Remote sensing technology to quantify salinity and water stress effects on forage yield can be an important tool to address yield loss potential when deficit irrigating with poor...

Salinity in Florida Bay is closely related to water management in South Florida. Water management activities over the last century have disrupted the quantity, quality, timing and distribution of freshwater flows into Florida Bay affecting salinity conditions. The main goal of the project presented in this paper is to accumulate all the data available on salinity in Florida Bay into one databas...

There is currently a large regional effort to restore tidal marsh ecosystems in the San Francisco BayDelta Estuary involving the commitment of hundreds of millions of dollars and broad landscape-scale habitat manipulations. Although climate change has been on the horizon for many years, recent developments suggest that it must be taken seriously as a factor to be considered in future planning f...

This paper presents a method for predicting areas at risk from dryland salinity using information derived from multi-temporal Landsat Thematic Mapper satellite images combined with landform data derived from high-quality digital elevation models. The method aims to reproduce expert opinion about the future extent of salinity by using decision trees to determine the relationship between salinity...

abstract irrigation planning and management requires continious monitoring and measurements of soil moisture content. application of gypsum blockes (gb) are common in soil moisture measurements. gb readings are subjected to its geometry and soil solution concentration. this study was carried on 90 gb in research greenhouse of faculty agricultural, ferdowsi university of mashhad. at the begining...
