Irrigation Adaptation to Changing Water SupplyMarwan Haddad
1) Israel began constructing a separation barrier between the West Bank and Israel in 2002 without international consent. This barrier has negatively impacted Palestinians by confiscating farmland, destroying irrigation infrastructure, and limiting access to water resources.
2) The document analyzes how Palestinian farmers have adapted to cope with these impacts, such as increasing water storage capacity and documenting land/water resources. However, the barrier still undermines Palestinian livelihoods and violates international law.
3) Over a third of Palestinians will be separated from the West Bank by the barrier's completion. The International Court of Justice ruled Israel must dismantle the barrier and compensate Palestinians for losses due to its illegal construction.
Fate and Mobility of Glyphosate Leachate in Palestinian Soil Using SoilMarwan Haddad
This document summarizes a study on the fate and mobility of glyphosate leachate in Palestinian soil using soil column experiments. The key findings are:
1) Using column studies, the amount of glyphosate in soil decreases with increasing soil depth, with the highest levels found in the 0-30cm layer.
2) Increasing the concentration of glyphosate applied also increases the amount of glyphosate found in leachate, with 25x concentration having the highest levels.
3) The behavior of glyphosate leachate fits first-order reaction kinetics and adsorption isotherm models, indicating glyphosate adsorbs well to soil.

limestone contactors- steady state design relationshipsMarwan Haddad
This paper presents a steady-state model for the design of limestone contactors. The model relates key design parameters like the depth of limestone required, influent and effluent water chemistry, limestone properties, and operating conditions. As acidic water passes through a packed bed of crushed limestone, calcium carbonate dissolves, increasing the pH, calcium concentration, and alkalinity of the water. The rate of limestone dissolution depends on the transport of calcium ions away from the limestone surface. When the pH at the surface drops below 9.5, the dissolution rate is controlled solely by ion transport away from the interface.
