In areas of heavy snowfall like Niigata Prefecture, this will cause the seasonal patterns of river runoff to change,and will greatly influence the availability of water resources for agriculture. Our objective here is to forecast the changein the seasonal and monthly runoff volumes resulting from these future climate change scenarios, especially changes in thespring snowmelt runoff.Snowmelt Runoff Model (SRM) was applied to the Takiya River basin to simulate daily runoff over the period 2000-2007. Snow accumulation and melt was simulated for each of three elevation zones using air temperature data at high andlow elevations to estimate the lapse rate. Key model parameters were determined by analysis of the basin monthly waterbalance, in addition to model calibration using river discharge and snowpack snow water equivalent.The Japan Meteorological Agency has published regional scenarios that are based on the IPCC worst case ScenarioA2. Simulation of the IPCC Scenario A2 for Niigata region showed that runoff would be 2-3 times greater in winter (Dec-Feb),and decrease by half in spring (Apr-May). Changes in monthly runoff volumes are most sensitive to warming in the range+1.0～3.0℃ because large shifts occur in the proportions of snow versus rain. In Niigata, and other regions that receiveheavy snowfall at temperatures close to 0℃ , a small rise in temperature causes large changes in the size of the seasonalsnowpack and the seasonal distribution of runoff. Therefore, it is necessary to urgently review disaster prevention and waterresources management in such areas.", "subitem_description_type": "Abstract"}, {"subitem_description": "IPCC（気候変動に関する政府間パネル）によると、日本地域は2100年ごろまでに平均気温が２～３℃上昇し、降水量にも変化がおこる可能性が高いと言われています。新潟県のような積雪量の多い地域では、季節ごとの河川の流出量に大きな影響を与え、農業用水資源の利用にも影響があるでしょう。この研究では、将来の気候変動シナリオ( 特に春の融雪流出の変化) から、季節ごと、月ごとの流出量の変化を予測しています。Snowmelt Runoff Model を2000年から2007年の滝矢川（新潟県村上市旧朝日村）の流量データに適用させ、毎日の流出量を予測できるモデルを確立します。積雪量と融雪量は、標高ごとに分けた3つの流域エリアで、気温データによる割増係数を用いて決定しました。モデルの主要な係数は、河川の流量と積雪水量の実測値を用いた、月ごとの水収支の分析で決定しました。気象庁は気温の上昇が「最悪の場合」のIPCC A2シナリオに基づいて、それぞれの地域の気温上昇シナリオを発表しています。このシナリオを用いてにSnowmelt Runoff Model よる予測をすると、新潟地域の滝矢川では、河川の流出量が冬期間(12月-2月)に2～3倍、春(4月-5月) に半減するという結果を示します。毎月の流出量は、雪と雨の割合で流出時期にずれが生じるため、気温の上昇が+1.0~3.0C の範囲で最も敏感に変化します。新潟及び周辺の地域では気温0℃付近で大量の積雪があるため、気温の僅かな上昇が、積雪量と流出量に大きな影響を与えます。このような地域では防災と水資源管理の早急な見直しが必要です。", "subitem_description_type": "Abstract"}]}, "item_7_full_name_3": {"attribute_name": "著者別名",
