Abstract

ZULHAKKI: Evaluation of Several Methodsof Determining Drainage ModulusinWetlandRicefieldSeiBerasSekataRegional SunggalDeli Serdang district, supervised bySUMONOandLUKMANADLINHARAHAP. The aim wastoquantify andto compare themodulusvaluesof wetlandricefield drainageinthe village ofSeiBeras Sekata. Drainagemodulusvalueis usedas a reference tothrow out waterfrom thewetland ricefield. Drainagemodulusvalueswas calculated bythreemethods i.eplottingmaximum dailyrainfall, dailyinundationsimulationswitha dailywater balancein themappedfields, and usingthe formulaofthe Departmentof Public Works. It was found from the research, thedrainagemodulusvalues ondaily maximumrainfallplottingmethodswas15 mm/day, the dailyinundationsimulation methodswithhighdailywater balancemappedfieldswas 40.3mm/day, andformulaof the Departmentof Public Workswas 44, 6 mm/day.
