Title

Hydraulics resistance is commonly used to simulate or replace drag and inertia forces due to vegetation when modeling tsunami run-up. A new numerical method was proposed which was named Combined Roughness and Reflected Model (CRRM). This method accommodates the reflection process of tsunami flow by tree surfaces. A series of experimental work was performed in laboratory to verify the numerical results. The physical process of laboratory work was discussed to explain the interaction between tsunami and vegetation models. The relation of some notable parameters was reviewed for both models. The physical model verified that the deviations between the physical and the numerical model were below 20%. With such numerical method, more challenging forest layout such as zigzag arrangement can be studied more accurately. It is concluded that the zigzag arrangement of trees layout and higher density of trees were capable of reducing tsunami run-up on land significantly.

Rainfall data is the main parameter to design drainage channel. The accuracy of rainfall data determines the accuracy of peak discharge estimation that is used for designing the drainage channel for flood mitigation purpose. The previous study presented that uncertainty of peak discharge is associated with the uncertainty of rainfall distribution and uncertainty of water holding capacity. The main purpose of this study is for understanding the sensitivity of rainfall data by comparing the estimated cost to construct drainage channel based on different values of peak discharges using two different rainfall data set which one rainfall data is created by considering 10% uncertainty of rainfall distribution. This study area is located on Plampang, Sumbawa Besar, West Nusa Tenggara. Results showed that the total cost to construct drainage channel increased by 15% if considering 10% uncertainty of rainfall.

Design of a Facility for Tsunami Run up Generation to Study Tsunami and Seawall Interaction Warniyati Warniyati; Radianta Triatmadja; Nur Yuwono; David S. V. L Bangguna

Experimental researches on the tsunami in the laboratory have been conducted using various methods. The use and techniques of tsunami wave generator depend on the objective of the tsunami observation to be conducted. When the objective is the scouring at the downstream of a seawall, the use of a short flume with control discharge seems to be appropriate. A valve with a mechanic controller was equipped to control the discharge from a reservoir into the flume. A numerical simulation of discharge into the flume and the overflow above the seawall was conducted to determine the dimension of the tsunami flume and its generator before construction. The experiments were conducted to simulate the hydrograph of tsunami overflow above the seawall model. The numerical hydrograph is found to be comparable with the experimental hydrograph. This indicates that the tsunami wave generator is capable of simulating tsunami hydrograph and ready for further use of simulations.

Sustaining Water-Related Heritage Infrastructures as Part of An Integrated Water Resource Management Program Radianta Triatmadja; Djoko Legono; Budi Wignyosukarto; Fatchan Nurrochmad; Sunjoto Sunjoto

The history of the water resources development in the world is generally inspired by the physical, climate and socioenvironment conditions such as geographical, culture and civilization at the local level. For many years, humans have spent tremendous efforts and time improving the quality of life through adequate water utilization. This research, therefore, aims to analyze the ancient water-related infrastructures as cultural heritages in creating a functional and adequate design. Data were obtained from the Mataram Canal in Yogyakarta Province which was selected due to the success story and various benefits associated with the Indonesian history of water resources in Central Java provinces. Today, some places along the canal have become tourist destinations, and it is more popular in Yogyakarta due to its architectural history. However, the diversification of water utilization in fishery ponds along the canal and the shift in land utilization from rice field to housings, and government buildings may undermine the function of the canal. The factual condition associated with the periodic decrease in irrigation command does not make the Mataram Canal useless. Therefore, efforts to maintain its function through restoration, and revitalization, can enhance water supply for irrigation and other purposes such as fish ponds and, pollutant dilution. The Strength-Weakness-Opportunity-Threat (SWOT) method with some key performance indicators was adopted to access the necessity of the sustainability program of the Mataram Canal as the heritage infrastructure. Some key performance indicators related to Integrated Water Resources Management (IWRM) program in Indonesia were introduced and utilized to prioritize the necessary actions. The results showed that the SWOT analysis promotes various actions to support the IWRM-related program of Mataram Canal. Furthermore, the implementation of the promoted actions would contribute to the longer sustainability of the Mataram Canal.
