AbstractThe research aimed at studying the effect of(Municipal-Solid-waste)depth (MSW-D) and their degradation time (MSW-T) on the quality and quantity of leachate produced (L-Q&Q), and the effect of(MSW-D) on rapiddegradation (phase converting rate) and dilution factor (D.F)(wash out during rainy seasons). It also aimed at design a-statistical-modeland equations to link (MSW-D) and (MSW-T) with (L-Q&Q). A study of (48) leachate samples for 12th(time-levels),4th(depth-levels) showed that the leachate volume reduced with (MSW-D) or (DT) increasing, and the leachate strength changed positively with (MSW-D) and inversely with (DT) so the (COD, NH4-N, TSS, EC) concentrations were increased with (MSW-D). It also showed that the rapidity degradation and (D.F) changed inversely with (MSW-D),and that (D.F) increased with increasing of(MSW-T) during rainy seasons. Thestatistical-model results showed that the (MSWD) and (MSW-T) were significantly affected (within-5%confidence-level) on (L-Q&Q), andthat (MSW-D) was more effective than (MSW-T).
