Abstract
Penelitian ini dilakukan di perairan Estuari Sungai Wonokromo yang berlokasi
di Wonorejo. Pada daerah muara sungai sering kali terjadi proses sedimentasi
dan erosi pada permukaan dasar perairan. Oleh karena itu penelitian ini
dilakukan untuk mengetahui perubahan morfologi dasar perairan muara Sungai
wonokromo dengan menggunakan pemodelan software MIKE 21. Untuk
mengetahui pola aliran arus di area penelitian digunakan Module Hydrodynamic
dan Module Mud Transport untuk mengetahui perubahan morfologi pada
permukaan dasar lokasi penelitian. Dari penelitian didapatkan hasil kecepatan
rata-rata arus pada saat simulasi di muara sungai adalah sekitar 0.029 - 0.095
m/s. Nilai konsentrasi sedimen rata-rata saat pasang adalah 7.1 kg/m3 dan saat
surut adalah 8.7 kg/m3. Pada daerah lokasi mengalami sedimentasi ditunjukan
dengan perubahan profil dasar perairan di daerah sungai menuju ke arah muara
berkisar 0.11 meter hingga 0.17 meter, dan profil dasar perairan di daerah muar
menuju ke laut pengalami perubahan berkisar 0.07 meter hingga 0.19 meter. Dari
hasil data penelitian ini diharapakan dapat berguna untuk proses pengambilan
keputusan dalam pengembangan lahan di kawasan Wonorejo.

This observation located at Wonorejo in Wonokromo River Estuarine. In
Estuarine areas happening a bed level change phenomena such as sedimentation
and erosion process. So this observation is conducted to know how much bed
level changing in Wonokromo River Estuarine. Therefore, this study was
conducted to determine the basic morphological changes in wonokromo estuary
using modeling software MIKE 21 to determine the pattern of current flow in the
study area using Hydrodynamic Module and Mud Transport Module to determine
the morphological changes on the surface of the base sites. The research showed
the average speed of the current at the time of the simulation at the river mouth is
about 0.029 - 0.095 m/s. The value of the tidal average sediment concentration is
7.1 gr/m3 and recede at 8.7 gr/m3. In areas those are experiencing sedimentation
indicated by changes in the basic profile in the area of the river waters towards the
estuary ranging from 0.11 meters to 0.17 meters, and the profiles in the estuary to
pengalami waters changes ranging from 0.07 meters to 0.19 meters. From the
results of this research the data is expected to be useful for decision-making
processes in the development of land in the area Wonorejo.
