BAB IV PEMODELAN DAS BERINGIN LAMPIRAN

=================================================================

LAMPIRAN

Pemodelan DAS Beringin Dengan Menggunakan Parameter Pembanding.

Setelah seluruh data dan parameter dari DAS Beringin untuk kondisi sebenarnya

dimasukkan, maka akan dibuat suatu parameter pembanding, pada kasus ini kami

menggunakan perubahan parameter pada % Impervious “Perubahn Tata Guna

Lahan”didapat output seperti dibawah ini.

Dengan parameter Impervious = 10 %

Parameter – Parameternya adalah :

• Slope =1,3 %

• Imperv =10%

• N – Imperv = 0,012

• N – Perv = 0,012

• Dstore – Imperv = 0,05

• Dstore – Perv = 0,05

• Zero Imperv = 25 %
