We need to de-silt and dredge rivers in Bulacan and Pampanga. We need to deepen the riverbeds and increase their carrying capacity so that come heavy rains, flood waters would flow more quickly.)</p><ul class="op-related-articles">	<li><a href="https://news.abs-cbn.com/video/news/08/03/23/several-bulacan-pampanga-towns-remain-flooded">Several Bulacan, Pampanga towns remain flooded</a></li></ul><p>The DPWH also needs help from local governments and the environment department to strengthen reforestation because soil erosion contributes to flooding, Bonoan said. </p><p>&quot;Yung erosion from the mountain slopes dito sa may Bulacan area ay very loose na. Siyempre yung erosion ng lupa d’yan pumupunta sa ilog, kaya [bumababaw] rin talaga yung riverbeds,&quot; he said. </p><p>(Soil in the mountain slopes in Bulacan is very loose. Eroded soil goes down to the rivers and makes the riverbeds shallower.)</p><p>The lack of comprehensive drainage programs in some subdivisions and towns &quot;is exacerbating the situation,&quot; Bonoan said. </p><p>&quot;Siyempre ‘pag umapaw yung tubig-baha sa ilog, it will remain doon sa kanilang lugar [dahil walang drainage plan],&quot; the DPWH chief said. </p><p>&quot;Again, I think land use program is also very important para makita natin yung mga drainage system at saka kung saan dapat magkaroon ng mga developments para maibsan natin yung mga ganyang problema. Kasi alam na natin na flooded areas yung mga lugar na ‘yan and yet, kung minsan pinapagayan pa rin natin ipapatayo mga subdivisions,&quot; he continued. </p><p>(Of course, water from the rivers will remain in their area if they have no drainage plans. Again, I think the land use program is also very important so we could see the drainage system and where developments should be located so that we can prevent flooding. We already know which areas are flooded easily and yet, sometimes, we still allow subdivisions to be built.)</p><ul class="op-related-articles">	<li><a href="https://news.abs-cbn.com/news/08/03/23/recent-bulacan-floods-ondoy-like-governor">Recent Bulacan floods Ondoy-like, says governor</a></li></ul><p>Pampanga and Bulacan were among several areas which declared a state of calamity due to floods spawned by heavy rains from the habagat and typhoons Egay and Falcon. </p><ul class="op-related-articles">	<li><a href="https://news.abs-cbn.com/news/08/03/23/egay-habagat-leave-p7-b-worth-of-damage-to-roads-bridges-dpwh">Egay, habagat leave P7-B worth of damage to roads, bridges: DPWH</a></li></ul><p>The weather in parts of Luzon is expected to gradually improve from Friday as Falcon moved farther away from the country, weather forecaster PAGASA said. </p><ul class="op-related-articles">	<li><a href="https://news.abs-cbn.com/news/08/04/23/weather-to-slowly-improve-as-habagat-weakens-pagasa">Weather to gradually improve as habagat weakens: PAGASA</a></li></ul><div><em>For more updates, visit the <a href="https://news.abs-cbn.com/weather" target="_blank">ABS-CBN weather center</a>.</em></div><figure class="op-interactive"><iframe allow="autoplay; fullscreen" frameBorder="0" height="100%" id="ivsplayer01" scrolling="no" src="https://player.ivideosmart.com/ivsplayer/v4/dist/html/iframe-src.html?iframeid=ivsplayer01&amp;key=e8c22c015ca9eafa76f1e3edfa03c603&amp;spid=3001339&amp;vid=2741629" width="100%"></iframe></figure><div class="iwantbar">Watch more News on <a href="https://www.iwanttfc.com/#!/browse/Genres/News/tag_id_genres/id_news" target="_blank">iWantTFC</a></div><figure class="op-interactive"><iframe allow="autoplay; fullscreen" frameBorder="0" height="100%" id="ivsplayer01" scrolling="no" src="https://player.ivideosmart.com/ivsplayer/v4/dist/html/iframe-src.html?iframeid=ivsplayer01&amp;key=e8c22c015ca9eafa76f1e3edfa03c603&amp;spid=3001339&amp;vid=2742472" width="100%"></iframe></figure><div class="iwantbar">Watch more News on <a href="https://www.iwanttfc.com/#!/browse/Genres/News/tag_id_genres/id_news" target="_blank">iWantTFC</a></div>
