IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

The integrated hydrologic modeling as a key for sustainable urban water planning in the gaza strip
Author : TAMER ESHTAWI1, MARIELE EVERS2 AND BERNHARD TISCHBEIN3
ABSTRACT
This study demonstrates the strength of using integrated hydrologic modeling in the sustainable urban water planning
process. It provides a holistic view of the urban water ecosystem of the Gaza Strip, quantifies the urban water budget
interaction with sufficient spatial and temporal details, and supports realistic scenarios inferred from the decision making
agenda. A coupling of the surface water (SWAT), the groundwater (MODFLOW) and the solute transport (MT3DMS
package) models was performed to quantify surface-groundwater and quantity-quality interactions due to the impacts of
urban area expansion. The results indicate a good fit between measured and simulated nitrate and chloride
concentrations. The responses of the groundwater level, the nitrate concentrations (related to human activities) and the
chloride concentrations (related to seawater intrusion) to urban area expansion and corresponding changes in urban water
budget were examined on a macro scale level. The potentials of non-conventional water resources scenarios, namely
desalination, stormwater harvesting and treated wastewater reuse were investigated. In a novel analysis, the opportunity
for groundwater improvement and deterioration under each scenario were articulated and discussed in spatial-temporal
and statistical approaches. The quality deterioration cycle index was estimated as the ratio between the amounts of low
and high quality recharge components within the urban water ecosystem that predicted of year 2030. The spatial
sustainability index for the groundwater quantity (SIQ) and the spatial sustainability index for the groundwater quality (SIC)
were developed for the targeted scenarios as measures of their effectiveness toward sustainable groundwater.
