Optimum allocation of water for restoration Iraqi marshes is essential different related authorities. Abo-Ziriq marsh area about 120 km2 situated 40 km east Al-Nassryia city. After comparing the measured annual qualities with standards surface quality evaluation, was in acceptable limit. Hydro balance computation were done each month by using interface among HEC-RAS, HEC-GeoRAS and ArcView GIS ...

The rational utilization of unconventional water sources is great significance to areas where conventional resources are scarce, and resource allocation an important way realize the distribution multiple sources. This paper constructs a system integrating model data parameter database, supply demand prediction module, groundwater numerical simulation module module. Taking brackish as main resea...

Historically, water allocation focused on quantities demanded by consumptive uses. As quantity demand grows, efficient allocation among consumptive and nonconsumptive uses becomes more critical. This hedonic approach provides information regarding recreational and aesthetic (RA) value for a central Texas lake. The model indicates several statistically significant RA characteristics of housing; ...

This paper considers the issue of optimal subcarrier allocation in OFDMA. We show, via a counter example, that water-filling based subcarrier allocation policies, contrary to conventional wisdom, fail to provide rate-stability for an otherwise stabilizable OFDMA system. Water-filling is too myopic when considering longtime average performance, e.g. delay, queue lengths, and even long-run throug...
