Banjir merupakan salah satu masalah utama yang melanda kota-kota yang berada di pinggir sungai, termasuk Kota Jambi yang berada di hilir Batanghari. Untuk meminimalisasi kerugian akibat banjir, mitigasi bencana banjir melalui pemodelan wilayah banjir menjadi penting. Penilitian ini mengkaji pemodelan spasial di Kota Jambi dengan menggunakan variabel ketinggian tempat, tinggi muka air sungai, curah hujan, koefisien limpasan dan kedalaman banjir. Survei lapang pada 17 lokasi yang hasilnya dikaitkan dengan informasi hasil pengolahan data, selanjutnya dilakukan analisis statistic untuk melihat keterkaitan antar variabel dan pemodelan wilayahg banjir berbasis grid dilakukan dengan menggunakan software ArcGis 9.3. Hasil yang diperoleh menunjukkan bahwa peristiwa banjir di Kota Jambi cenderung meningkat dari tahun 2001 sampai 2005, baik dari segi frekuensi kejadian maupun luas wilayah banjir. Hasil pemodelan banjir di Kota Jambi menunjukkan bahwa wilayah yang sering terendam banjir berada di bagian utara dan timur Kota Jambi dan berada di sepadan sungai. Kota Jambi mulai terendam banjir pada saat tinggi muka air Batanghari mencapai angka 11 m, yang terjadi di Kelurahan Pasir Putih dan Tahtul Yaman. Semakin tinggi muka air Batanghari, semakin luas wilayah yang berpotensi tergenang air. ......Floods are one of the main problems that plagued the cities on the shores of the River, including the city of Jambi in Batanghari downstream. To minimize losses due to floods, the disaster mitigation of flooding through the modeling of the region from floods is important. This study examined the spatial modeling in Jambi by using variable high altitude, river water, rainfall, runoff coefficient and depth of flooding. Field surveys at 17 locations that the results related to the information the results of data processing, statistical analysis was then performed to see the relationship between variables and application of grid-based model of flood zones is done using the software ArcGIS. 9.3. Result obtained showed that the incidence of flooding in the city of Jambi is likely to increase from 2001 to 2005, both in terms of frequency of occurrence and level of flooding. The results of modeling of floods in the town of Jambi shows frequently flood areas in northern and eastern cities, and rivers are commensurate Batanghari. Jambi City began under water at high water level reaches 11 m Batanghari, which occurred in the village of Pasir Putih and Tahtul Yaman. If water level of Batanghari showed a high value, the potentially flooded are also larger.

ABSTRACT
Water Sensitive Urban Design WSUD systems have the potential prevent the hydrologic disturbance and water quality concern associate with storm water runoff due to land change from urban development. WSUD have been strongly recommended to be used and new developments in every city in Australia are regulated. However, Indonesia still developing the rule but not deeply studied the idea and concept of WSUD. The objective of this research is to comparing available system in sustainable city of case study to the concept that is used in Australia. The main idea of why it is applied in Australia is due to most of the land use are impervious area which is increase in runoff peak and develop industrialize region.

ABSTRAK
Water Sensitive Urban Design WSUD system memiliki potensi mencegah gangguan dan menambah kualitas air dari limpasan air hujan akibat perubahan lahan dari pembangunan perkotaan. WSUD telah disarankan untuk digunakan dalam perkembangan baru di Australia. Indonesia masih mengembangkan aturan tetapi tidak mendalam mempelajari ide dan konsep WSUD. Tujuan dari penelitian ini adalah untuk membandingkan sistem yang tersedia di kota yang berkelanjutan dari studi kasus dengan konsep yang digunakan di Australia. Ide utama mengapa konsep WSUD diterapkan di Australia adalah karena industrialisasi sebagian besar penggunaan lahan hijau berubah dan mengakibatkan puncak limpasan besar.

Hydrology plays important role in urban development thus hydrologic event that occurs has to be accurately estimated in order to satisfy the needs of the area in infrastructure. The advance technology has helped the engineers to model the event which should lead into better decisionmaking and visualisation in undertaking most hydrological cases. This thesis reviews four urban hydrological modelling softwares and discusses the essential components of the modelling that includes catchment model, loss model, storage discharge relations, and its input parameters. The aim of the review is to provide basic understanding of the hydrology processes by using modeling software in accordance to the basic theory and standard design. The review does not seek to be a comprehensive technical of urban hydrology management and modelling.
