The key point for successful tidal swamp land area management is /lIe ability of farmers to control water table at tertiary block TI}e effort to fulfill water requirement is depended on GoneMion of water network system and water control structures. The objective of this study was to analyze the existing water network system and to develop the recommendation for water network improvement in order to increase the planting index. Study area is at Telang Karya Village, Delta Telang I Primer 8. The methods used in this study were survey and monitoni}g. The computer model of DUFLOW was used 10 determine channel storage capacity and to observe the effect of water system operation on water dynamics Witl}/n channel. Secondary block of P8-12S was used as {J bouncla(1j condition Results of simulation showed t1wt the land can be classified as A tYPhology in w/7ich high tidal water flow was capable to irrigate tl7e land during wet and dry seasons. Channel storage capacity was sufficient and no water overflow through embankment. Drainage or outflow potential was velY low especially (juring wet season because low tidDI period WD$ insufficient to discharge rainfall water and /7igh tide water had alreDdy entered w/'Ien the outflow process had not already finished yet, Therefore, this condition requires control structures. WCJter chDnnel type gate having diameter of 50 em and equipped witl} valve gate is very effective in controlling water. Evaluation showed that gate operation at maximum drainage at December February period conducted during wet season was capable to provide water flooding condition of 10-15 cm on land surface, control option during February-April period was one way flow (supply drainage gates), and maximum drainage during dry season that capable to decrease water table within 30-50 em below soil surface This condition was capable to maximize the land potential for three times planting (PI of 300). that consisted Of rice-rice-corn.
